Heart, Vascular and Thoracic Care Causes. Up to 80 percent of aortic aneurysms are caused by hardening of the arteries (atherosclerosis). Atherosclerosis can develop when cholesterol and fat build up inside the arteries. High blood pressure (hypertension), cigarette smoking, family history and age also contribute to atherosclerosis.

Types of Aneurysms An aortic aneurysm is a weakened or bulging area on the wall of the aorta. An abdominal aortic aneurysm occurs when the large blood vessel (the aorta) that supplies blood to the abdomen, pelvis and legs becomes abnormally large or balloons outward.

Overview Most aortic aneurysms occur in the part of your aorta that's in your abdomen. Although the exact cause of abdominal aortic aneurysms is unknown, a number of factors may play a role, including: Tobacco use. Cigarette smoking and other forms of tobacco use appear to increase your risk of aortic aneurysms.

Aortic aneurysm An aortic aneurysm is an enlargement (dilation) of the aorta to greater than 1.5 times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain. They are most commonly located in the abdominal aorta, but can also be located in the thoracic aorta. Aortic aneurysms cause weakness in the wall of the aorta and increase the risk of aortic rupture. When rupture occurs, massive internal bleeding results and, unless treated immediately, shock and death can occur.

Abdominal Aortic Aneurysm An abdominal aortic aneurysm is a weakened and bulging area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta runs from your heart through the center of your chest and abdomen. Most commonly, people with abdominal aortic aneurysms are Caucasian, male, and older than 60, and have high blood pressure, atherosclerosis, or a family history of aortic aneurysm. A history of cigarette smoking is also a strong risk factor for the development of abdominal aortic aneurysm. Abdominal aortic aneurysms are estimated to occur in 1.3% of men aged 45 to 54 years of age and 12.5% of men between 75 and 84 years of age in the United States (Source: CDC).

Aortic Aneurysm - Topic Overview An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst.

Overview Tears in the wall of the aorta (dissection) and rupture of the aorta are the main complications of thoracic aortic aneurysm. A ruptured aortic aneurysm can lead to life-threatening internal bleeding. In general, the larger the aneurysm, the greater the risk of rupture.

Enlarged Aorta â Causes, Symptoms of an Aortic Aneurysm An aortic aneurysm is the abnormal enlargement of a portion of the aorta. It arises when a segment of the vessel wall is weakened due to any number of factors and this causes a bulging. This can be a balloon-like bulge known as a saccular aneurysm or a widening of an entire segment of the aorta which is called a fusiform aneurysm.

Aortic Aneurysm Fact Sheet Aortic aneurysms work in two ways: 1  The force of blood pumping can split the layers of the artery wall, allowing blood to leak in between them. 2  The aneurysm can burst completely, causing bleeding inside the body. 3  Dissections and ruptures are the cause of most deaths from aortic aneurysms.

Aortic Aneurysm 1 False aneurysms are usually a result of an infection. 2  Because the abdominal aorta is such a large vessel, a ruptured abdominal aneurysm is a life-threatening event.  Fortunately, not all aneurysms rupture right away. Many grow very slowly and cause no symptoms or problems for many years.

- note instead of causing a bulge in a thinned artery wall aortic aneurysms occasionally occur between layers of the artery itself blood starts to flow in the separated artery layers cutting off blood flow in the artery this condition can rapidly lead to rupture of the artery

Thoracic Aortic Aneurysm and Aortic Dissection An aortic aneurysm is a bulging, weakened area in the wall of the aorta. Over time, the blood vessel balloons and is at risk for bursting (rupture) or separating (dissection). This can cause life threatening bleeding and potentially death.

Abdominal aortic aneurysm Abdominal aortic aneurysm. The aorta is the main blood vessel that supplies blood to the abdomen, pelvis, and legs. An abdominal aortic aneurysm occurs when an area of the aorta becomes very large or balloons out. The exact cause of an aneurysm is unknown. It occurs due to weakness in the wall of the artery.

10 Common Causes of Abdominal Aortic Aneurysms 1. Poor Diet. Medical research links the hardening of the arteries (a condition referred to as Atherosclerosis) with the development of an abdominal aortic aneurysm due to the accumulation of fat and other substances on the lining of a blood vessel. This fatty build-up is responsible for amplifying the risk of an aneurysm.

Aortic Aneurysm - Topic Overview An aortic aneurysm can also lead to other problems. Blood flow often slows in the bulging section of an aortic aneurysm, causing clots to form. If a blood clot breaks off from an aortic aneurysm in the chest area, it can travel to the brain and cause a stroke.Blood clots that break off from an aortic aneurysm in the belly area can block blood flow to the belly or legs.n aortic aneurysm can also lead to other problems.

- Subject: Shimmy or Speed Wobble. From: Jobst Brandt. Date: June 25, 2004, revised February 25, 2005. Shimmy, a spontaneous steering oscillation of the front wheel, usually occurs at a predictable speed when riding no-hands. The likelihood of shimmy is greatest when the only rider-to-bicycle contact is at the saddle and pedals. This position gives the least damping by hands, arms, and legs.

- @EarlyForest -- Sometimes tortuous aortas can indirectly cause abdominal aortic aneurysms, like pharmchick78 was talking about. Since a tortuous aorta is abnormal, sometimes the wall of the aorta can be weaker, leading to an aortic aneurysm, or, worst case scenario, an aortic aneurysm rupture.EarlyForest -- Sometimes tortuous aortas can indirectly cause abdominal aortic aneurysms, like pharmchick78 was talking about.

Aneurysms can occur in any blood vessel in the body, but the most common type arises in the largest artery in the bodyÃ¢â¬âthe aorta. This condition affects over 200,000 Americans and is referred to as an Abdominal Aortic Aneurysm (AAA).

Aortic Disorders A thoracic aortic aneurysm (TAA) may not cause symptoms until it dissects or grows large. If you have symptoms, they may include: Pain in your jaw, neck, back, or chest Coughing and/or hoarseness; Shortness of breath and/or trouble breathing or swallowing; A dissection is a split in one or more layers of the artery wall.
